Standardized Sampling for Hemlock Woolly Adelgid

Sampling Publication Cover

The hemlock woolly adelgid (Adelges tsugae) is an introduced insect pest that has rapidly spread throughout many hemlock forests in the eastern United States.  The entire range of eastern hemlock (Tsuga canadensis) and the less common Carolina hemlock (Tsuga caroliniana) are at risk. The availability of a standardized sampling plan provides resource managers and the public an efficient and effective means to detect, characterize, and monitor hemlock woolly adelgid infestations.   Currently, this sampling plan is being widely adopted as a standardized practice to quantify and communicate the severity of adelgid infestations. The sampling method was designed to be easy and flexible to implement. Links to training resources are provided below.
